The Two U.S. States Not Connected to the Mainland

Of the 50 states, only Alaska and Hawaii lack a land connection to the contiguous United States.

Alaska

• Location: Northwest corner of North America.
• Separation: ~500 miles (800 km) of Canadian territory (British Columbia, Yukon) between Washington State and Alaska's panhandle.
• Access: By air (Anchorage, Fairbanks), sea (ferry via Inside Passage from Bellingham, WA), or road (Alcan Highway through Canada).
• Superlative: Largest state (663,300 sq mi), 1/5 the entire U.S. landmass.

Hawaii

• Location: Central Pacific Ocean, ~2,400 mi (3,860 km) from California.
• Geography: Volcanic archipelago of 137 islands; eight main islands.
• Access: Exclusively by air (Honolulu/HNL hub) or multi-day cruise.
• Superlative: Only state in Oceania; most isolated population center on Earth.

Historical Note

Both were territories until 1959: Alaska admitted Jan 3 (49th), Hawaii Aug 21 (50th). Their non-contiguity shapes defense logistics, shipping costs, time zones (AKST/HST), and unique ecosystems.
